This monograph, developed to provide some ideas about the initial considerations of an agency contemplating the use of auxiliary personnel, describes the types of auxiliary positions that might be established, administrative planning necessary and the factors to consider in developing and establishing the positions. The decision to use auxiliary personnel is based on the conviction that there are differential needs of clients that may be met by persons with an educational and experience background in fields other than social work. Auxiliary positions relating to administrative procedures are: administrative aide, research and statistical assistant, and welfare assistant. Those in direct service to the clients might be a household helper and homemaker, or a neighborhood worker. Specific details are described for assessment of needs, scope and content of services, analysis of organization and staffing patterns, restriction of jobs, written politices, supervision and training, program evaluation, and community relationships. Illustrative job specifications for use in the development of class specifications for auxiliary positions for family services in public welfare agencies are included, together with information on how to adapt and interpret them to reflect specific programs, job content, and agency organization.
